You have a very interesting website. Do you feel lonely? Your website portraits you as a sad person who has suffered a lot. I wouldn't say you are insignificant at all :) You do certain seem to be quite significant probably to more people than you realize even if it isn't to all the people you wish to be significant to.

I feel the best way to do what you seem to want to do is by meeting people where they are. No matter what you do, the last part of your mission relies on the lonely person. They have to choose to connect to others and then they have to do it. Arguably, that's the hardest part.
